    摘要: An oil pump apparatus, including a pump mechanism portion for discharging operating fluid, a valve-receiving bore formed in a housing, a flow control valve arranged in the valve-receiving bore connected to a bypass hole, and a bypass passage. The bypass passage is connected to the bypass hole, having a space radially extending from an edge of the bypass hole in a fluid stream direction of the excess operating fluid spouting from an opening area of the bypass hole. When fluid stream of the excess operating fluid reaches the inner surface of the bypass passage, the pressure of the excess operating fluid has been weaken sufficiently because fluid stream of the excess operating fluid is diffused by the long span of the bypass passage extended from the edged of the bypass hole. Therefore, the inner surface of the bypass passage is protected from cavitation damages and erosion.

    摘要: A variable transmission ratio apparatus for effectively preventing ratcheting between a flexible spline and a circular spline caused by a steering operation performing in a locked state. A variable transmission ratio apparatus includes a strain wave gear mechanism for adding rotation resulting from motor drive to rotation from an input shaft resulting from a steering operation and transmitting the added rotation to an output shaft, a housing accommodating the strain wave gear mechanism and the motor and fixed to a non-rotating portion, and a lock device for locking the housing and a motor shaft in a manner prohibiting relative rotation therebetween. Among the circular splines forming the strain wave gear mechanism, the number of teeth of the circular spline connected to the output shaft is greater than the number of teeth of the circular spline connected to the input shaft.
